APPARATUS FOR MAKING EXTRACTS FROMVEGETABLE SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 253,802,1dated February 14, 18 82.

Application filed July 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, MORRIS WISE, a citizen of the United States, residing at New York,

- in the county and State of New York, have invented new paratus for Substances, fication.

This invention relates to apparatus for obtaining extracts from pimento-leaves and other and useful Improvements in Ap- Making Extracts from Vegetable vegetable substances by the action of steam and water; and it consists in the combination, with a distilling-tank, of a foramiuous false bottom constructed with a central upwardlyprojectiug hollow foraniinous stem having laterally-projecting hollow foraminous branches, so that if steam isadmitted to the tank below the false bottom itrises not only through such bottom, but also into and through the foraminous stem and its branghes, whence it escapes, thus thoroughly diifusingitself iu'the contents of the tank. With the tank and its said false bottom are combined a secondary foraminous false bottom, and a steam-supplypipe which,

' sents a vertical central section.

is connected to the tank between the two false bottoms, so that the secondary false bottom has a tendency to retard the escape of live steam, at the same time allowing the escape of the water of condensation.

This invention is illustrated in the accompanying drawings, in which Figure l-repre- Fig. 2 is a horizontal section of the distilling-tank.

Similar letters indicate corresponding parts.

The letter A designates the distilling-tank; B, the primary false bottom; 0, its stem havingbrauches D; E, the secondary false bottom,

and F the steam-supply pipe.

The side of the tank A tapers toward its lower end, and its main bottom A is funnelshaped, the neck thereof being provided with a stop-cock, G, while the top A of the tank is removable, and is connected to a condensingcoi1, H, arranged in a cooler,- l. A strainer, J, moreover,is placed in the funnel-shaped bottom A, to prevent clogging.

The two false bottoms B E rest on shoulders k I in the tank, so that they are removable, and both are madeforaminous, as of perforated sheet metal, the lower or secondary false bot tom being, moreover, provided with a handle.

.of which the following is a specisteam-supply pipe F is connected to the tank A at a point between the two false bottoms B E, and-it is provided with a suitable stop-cock.

It will be seen that if the steam is admitted to the tank by the supply-pipe F it ascends through the primary false bottom B, as well asinto and through the stem 0 and its branches D, escaping therefrom through their holes, and in this manner the steam is caused to penetrate to every portion of the tank, and thus diifuse itself thoroughly in theleaves or other substance contained therein. The secondary false bottom E, moreover, has a tendency'to retard the escape of live steam in a lower direction, while it allows the escape of the water resulting from any condensation of the steam in the space between the two false bottoms.

In applying the apparatus to use the tank is filled with the substance from which an ex tractis to be madcsaypimento-1eaves-above the primary false bottom B, and the top A having been tightly closed, the cock of the steamsupply pipe F is opened. The steam thus admitted to the tank acts'on the leaves therein and escapes to the coil H, carrying with it. the

essential oil, and being thus condensed,iit is,

afterward, concentrated and purified. When the leaves have been thus freed from the eslsential oil the steam is shut off, and the leaves are rem ovcd, to bc'subsequentl y treated with water in a suitable vessel for the purpose of charging the same with the astringent matter contained in the leaves.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, with a distilling-tank,

of a foraminous false bottom provided wit-h an attached foraminous verticalstem having lateral foraminous branches, substantially as described, whereby the stbam admitted beneath the false bottom will enter the tank through the false bottom and through the stem and its branches, as and for the purpose set forth.

2. The combination, substantially as hereinbefore set forth, with the distiiling-tank A, of my hand and seal in the presence of two sub the" pgimary foraminousEfalse bottom B; the scribing witnesses.
